May 26 (UPI) -- The Strait of Hormuz will be reopened "one way or the other," U.S. Secretary of State Marco Rubio warned Tuesday amid uncertainty over ongoing negotiations between the two countries after the United States attacked Iran hours earlier.

The U.S. military conducted what it called "self-defense" strikes in southern Iran on Monday night as Iranian negotiators were in Doha discussing a potential agreement aimed at ending the U.S.-Iran war.

Responding to reporters' questions about the effect the attacks may have on the already-fragile talks, Rubio suggested that Iran must remove restrictions from the vital energy trade route or risk further U.S. military action.

"Well, the straits have to be open. They're going to be one way or the other. So they need to be open," he said.
